DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The following description is intended to convey an understanding by providing specific embodiments and details. It is understood, however, that the present invention is not limited to these specific embodiments and details, which are exemplary only. It is further understood that any number of alternative embodiments may be implemented within the scope of the appended claims, depending upon specific design and other needs.

FIG. 1 is a schematic diagram of an environment where an embodiment may be implemented. An entity, by way of non-limiting example, a telecommunications company, may provide content or applications (collectively, “resources”) to any person connected to network 130, which may be the internet. Members of the public, entity employees or contractors may connect to network 130, using user computers 122, 124, 126. Each user computer 122, 124, 126 may include a monitor, keyboard and mouse. Through network 130, user computers 122, 124, 126 may access resources via servers as discussed presently.

User computers 122, 124, 126 are coupled via network 130 to routers 142, which act to, for example, screen ports. The entire system behind routers 142 (e.g., elements 142-185) may reside on a single domain or on multiple domains. By way of non-limiting example, routers 142 may allow connections with port numbers 80 and 443 only. Firewalls 144 are coupled to routers 142. Firewalls 144 serve as an additional layer of security. Firewalls 144 are coupled to switches 146. Switches 146 may perform load balancing using, by way of non-limiting example, a Cisco Softswitch, available from Cisco Systems, Inc. of San Jose, Calif.

A first set of servers 150 lie behind switches 146. Servers 150 may be, by way of non-limiting example, Internet Information Servers. Further, servers 150 may serve web pages, which may include one or both of content and applications. Such applications may be, by way of non-limiting example, billing applications that a user may use to pay bills electronically over the internet. Servers 150 may receive content and applications from additional servers as discussed below. Also coupled to switches 146 are domain name servers 152, which may allow for subdomain hosting.

Additional firewalls 160 lie between servers 150 and 152 on the one hand, and further servers and administrative hardware and software on the other hand. Such firewalls may provide an additional layer of protection by screening port traffic, for example.

Various servers 175, 180 and administrative hardware and software 170, 185 are coupled to firewalls 160. (Each server 150, 152, 170, 175, 180, 185 may include a display device, such as a monitor, and standard input devices such as a keyboard and mouse.) Application servers 175 may store and serve business logic such as, by way of non-limiting example, billing applications that a user may use to pay bills electronically over the internet. Each application server 175 may include multiple applications and may or may not include the same applications as other application servers 175. Domain controllers 170 assist in managing servers, users and resources inside of the domain, e.g., behind firewalls 144. Database servers 180 store and serve bulk data, such as billing records. By way of non-limiting example, database servers 180 may be SQL servers. Management servers 185 may be used to monitor and report usage of hardware and software in the system. By way of non-limiting example, management servers 185 may gather and report statistics on how database servers 180 are used.

In some embodiments, the same applications and content reside in each of servers 150, 175 and 180. In other embodiments, some applications and some content resides in some, but not all, of servers 150, 175 and 180. Further note that, in general, a user who attempts to access an application, such as a bill payment application, does not know which server will provide the application to the user. Typically, a user simply types a URL into a browser application (or clicks on a predefined bookmark), without knowing which physical device will provide the content or application that is associated with the URL or bookmark. For example, if a user attempts to use user computer 122 to access a resource that resides on more than one of servers 150, 175 and 180, the decision as to which server provides the user access to the resource is typically made automatically, without any knowledge of the user.

In some configurations, switches 146 are configured as load balancers, which work transparently to direct a particular user request to a particular server based on efficiency heuristics and routing algorithms. Thus, a user might type a URL for a bill payment application into the user's browser, which resides on user computer 122, and a load balancer might direct the user's request to one of servers 150, even though the same bill payment application might reside on each of servers 150 and 175. The next time the user types the same URL into the user's browser on user computer 122, the same load balancer might direct the user's request to a different server 150. In general, it is impossible for a user to know which server provides an application or content.

A problem known as an “outage” may arise in a situation when either one or multiple servers serve the same resource. During an outage, users are unable to access a particular application or content. This situation might arise when the a router, switch, server or servers associated with a particular application or content malfunction. When an outage occurs, users are unable to access that particular application or content until the responsible component(s) are repaired.

A problem known as a “partial outage” may arise in a situation when multiple servers serve the same resource. For example, one type of partial outage occurs when some, but not all, users are unable to access a particular application or content. That situation might arise when a server associated with a particular geographic area malfunctions, while other servers continue to operate normally. Another type of partial outage occurs when some (or all) users experience a slow response to the users' requests. This might occur when one or more servers malfunction, overburdening the remaining functional servers. Yet another type of partial outage may occur when a particular resource associated with a URL is unavailable to some or all users, yet other resources associated with that same URL remain available. Such a situation might arise when multiple servers are involved in serving multiple resources (e.g., a bill payment application and an account preferences display) that are associated with a single URL, and the server associated with a particular resource (e.g., the bill payment application) malfunctions, while the server associated with another resource (e.g., the account preferences display) continues to operate normally. Yet another type of partial outage occurs when one or more users are temporarily unable to access a resource. This might be caused by a sporadic malfunction in one or more servers.

When partial outages occur, it is generally difficult to pinpoint which server or servers is responsible. For example, a prior art technique for diagnosing the cause of a partial outage requires technical support staff to log in to each server separately in order to perform server health checks and configuration verifications. This technique takes a considerable amount of time. Certain embodiments improve on this prior art technique by allowing technical support staff to simultaneously perform server health checks and configuration verifications on a plurality of servers from a single access point, which may be remote from each server that is being diagnosed.

In general, certain embodiments allow entities, such as technical support staff, to view consolidated information about a plurality of servers and change parameters associated with one or more of the servers. The entity may be physically located at one of the servers and access the information (or change parameters) from that location, or may access such information (or change parameters) remotely. Thus, for example, an embodiment might allow an entity to view consolidated information about each of servers 150, 152, 170, 175, 180 and 185. In this example, the entity may access such information via any of servers 150, 152, 170, 175, 180 and 185, or may access such information via any of user computers 122, 124, 126. In some embodiments, servers accessed can be filtered by application, such that only servers associated with an application experiencing a partial outage are scrutinized.

According to certain embodiments, monitoring software may be installed in one or more of servers 150, 152, 170, 175, 180 and 185. In some embodiments, identical monitoring software may be installed in each server, in other embodiments, different monitoring software may be installed in different servers. The monitoring software installed in each server serves at least two purposes. First, the monitoring software controls a configuration process in which information specific to each server is stored in association with each server. That is, each server has access to one or more configuration files, which contain information regarding every server in the system. The configuration process is discussed in detail below, with reference to FIGS. 25-29. Second, the monitoring software allows an entity, such as a technical support staffer, to retrieve and modify parameters of any of the servers. Moreover, such parameter retrieval and modification can be affected from any server in the system. That is, any person with access to a single server may use the monitoring software installed in that server to retrieve and modify parameters associated with any other server in the system. The parameter retrieval and modification process is discussed in detail below in reference to FIGS. 2-24. Monitoring software according to some embodiments may be written in any, or a combination, of Visual Basic .Net (“VB.Net”), Windows Management Instrumentation (“WMI”), Visual Basic, Visual C++, ASP, PERL, Java, J2EE, C++, and others.

Once the monitoring software is installed, one or more configuration files are created. The configuration files include information about each of servers 150, 152, 170, 175, 180 and 185. More particularly, the configuration files indicate where information pertaining to each of servers 150, 152, 170, 175, 180 and 185 may be found. To create the configuration files, configuration information of each server in the system is gathered together and placed into one or more configuration files. These files are then stored such that each server in the system may access them, e.g., locally stored in each server's persistent memory. In some embodiments, each server has its own identical copy of the configuration files, locally stored on that server's persistent storage device. The configuration process is discussed in detail below, in reference to FIGS. 25-29.

In general, FIGS. 2-24 depict exemplary screens that an entity uses to access information about multiple servers and change parameters associated with one or more servers. Some embodiments include three main portions, a “Dashboard” portion, a “Comparison” portion, and a “Utilities” portion. In general, though functionality may overlap, a dashboard, embodiments of which are depicted in FIGS. 2-17, allows an entity to view consolidated information about a plurality of servers, while a comparison portion, embodiments of which are depicted in FIGS. 18-21, allows an entity to view consolidated information about a plurality of applications running on a plurality of servers. Additionally, a utilities portion, depicted in FIGS. 21-24, allows an entity to adjust parameters for a plurality of servers.
